DESCRIPTION

The VOT8121A consists of a GaAs IRLED optically coupled

to a photosensitive TRIAC packaged in a board space

saving DIP-4 package.

The VOT8121A isolates low-voltage logic from 120 VAC,

240 VAC, and 380 VAC lines to control resistive, inductive, or

capacitive loads including motors, solenoids, high current

thyristors or TRIAC and relays.
